... Cucurbit crops are grown throughout many Brazilian states and are affected by several viral diseases that represent one of the main constraints to cucurbit production in the country causing severe economic losses. During 2008-2015, a survey was performed in open-field of watermelon (Citrullus lanatus), melon (Cucumis melo), cucumber (C. sativus), pumpkin (Cucurbita spp.), chayote (Sechium edule), ...

... In the warm coast of Ecuador, cucumbers are grown in soil systems and open field. They present very low yields due to the long period of heavy rainfall and the presence of pests and diseases. The cultivation under protection and using a soilless system could be a solution to increase yield. The ontogeny of the Cucumis sativus cultivar 'Diamante' has been evaluated in four plots of 2400 m2 each fro ...

... The intensive production of cucumber is associated, among other techniques, with transplanting. The aim of this study was to compare the crop response of Cucumis sativus 'Diamante' depending on the planting method used. A split plot design was established: direct seeding or transplanting in a greenhouse and open field in order to evaluate the yield production. The trial was carried out in Vinces L ...

... Open field irrigated agriculture in arid to semi-arid regions of the world is seriously affected by frequent and severe droughts, limited water resources, and increased regulations restricting ground water use. Integrated strategies for melon (Cucumis melo L.) production can be applied to increase water savings without reducing marketable yields and product quality. These include selecting high-ef ...

... Watermelon is one of the most economically important agricultural crops all over the world. Aphis gossypii Glover is one of the major pests to feed on watermelon, not only resulting in a loss of yield and quality, but also as an important vector promoting plant viruses spread. To excavate excellent, anti-aphid watermelon germplasm, 21 germplasms were identified by combining of field and laboratory ...

... Powdery mildew is a severe disease caused by the fungus Podosphaera xanthii (Px) that reduces the melon production around the world. Genetic resistance is available in melon, but the reported alleles do not confer total resistance to all the pathogen races. In this study, the inheritance of the resistance of two new resistant sources was characterized. The accessions AM-55 and AC-15 (exotic types ...

... Ethylene is a gaseous hormone that controls many physiological and developmental processes in plants. In zucchini squash (Cucurbita pepo L.), it regulates important aspects such as sexual expression, monoecy stability, senescence and flower abscission, parthenocarpy, and postharvest fruit quality, including chilling injury. The identification and characterization of ethylene-insensitive mutants wi ...

... Cultivated Legenaria siceraria (Malign) Stanley is commonly known as the white-flowered gourd. It has been grown annually and it is a monocious, vigorous climber species. The mature fruit is often scooped out and the skin is used as containers, music instrument, decorative purposes or in some cases, fishing floats. Shoots, tendrils and leaves are also cooked and the seeds are removed for oil extra ...
